XPathFilterParameterSpec
public XPathFilterParameterSpec(String xPath)
Creates an
XPathFilterParameterSpec
with the specified XPath expression.- Parameters:
-
xPath
- the XPath expression to be evaluated - Throws:
-
NullPointerException
- ifxPath
isnull
XPathFilterParameterSpec
public XPathFilterParameterSpec(String xPath, Map<String,String> namespaceMap)
Creates an
XPathFilterParameterSpec
with the specified XPath expression and namespace map. The map is copied to protect against subsequent modification.- Parameters:
-
xPath
- the XPath expression to be evaluated -
namespaceMap
- the map of namespace prefixes. Each key is a namespace prefixString
that maps to a corresponding namespace URIString
. - Throws:
-
NullPointerException
- ifxPath
ornamespaceMap
arenull
-
ClassCastException
- if any of the map's keys or entries are not of typeString
Method Details

getNamespaceMap
public Map<String,String> getNamespaceMap()
Returns a map of namespace prefixes. Each key is a namespace prefix
String
that maps to a corresponding namespace URI String
. This implementation returns an unmodifiable map
.
